TBs TechChallenge, 2012 - Reverse 42002 (Hovercraft)



Here we're again for a new edition of  the TechREVERSE Challenge, in collaboration with the LEGO Technic product line - The fourth edition to be more precise. Thus we decided to bring one of the 1H2013 models into contest.

As usual, the challenge will consist in reverse-build one of the new models coming in 2013. Among the several possibilities I believe we have true challenge this time... and hope you enjoy it.
Again it is a model that doesn't include any new element to make things easier and more straight forward - This was not a mandatory criteria as we may have asked the participants to simply ignore eventual new element(s), or provide you with a quick mockup of the new element(s), like we did in 2009. However we decided to avoid it once more.

So and so the set selection for the current TechREVERSE Challenge issue is the 42002 (Hovercraft).


And then the challenge TBs for you, is exactly this!
Reverse and build your own digital reproduction from the 42002 main model, based on the product picture available so far.





Based on the successful experiment and results from the last year, we decided again to allow submissions made in any of the most common CAD tools in use by the FOLs to model their LEGO creations (LDraw/MLCadLDD and SR 3D Builder). 

Of course you may need to download and install any of these tools if you have not done it already before. Therefore some previous advices regarding LDraw installation may become handy.
Specially make sure you use the latest parts library available for the tool you're using. Otherwise it may negatively affect the ranking of your participation.

As for every contest, there must be some rules defined that will help us later to determine who's the winner, so read them carefully (small refinements on top of the previous edition).

Challenge Goal:
  • Reverse engineer and reproduce a digital model, from the Challenge proposed LEGO Technic set.
  • The reproduction should be exact (model complete assembly, parts list, colors and positioning).

Challenge Participation Rules:
  • Every contestant should submit his participation in the form of one single digital file, compatible with the latest version of one of the tools allowed in this contest (at contestant choice) - LDR, MPD, LXF or L3B.
    Hierarchical organization into sub-models is also allowed, for the tools supporting this.
  • The contestants are allowed to enter one single submission only (always the first one submitted). See the annotation made at the end of this post.
  • Each contest submission must include one single model only.
  • Contestants must also include one render image from their model, with a minimum resolution of 800x600 pixels.
    It would be great if you have skills for photo-realistic rendering, but not considered as criteria for the purpose of this contest evaluation.
  • Any eventual special elements in the model must be reproduced accordingly (e.g. flexible parts, shock absorbers, etc...). Reproduction should be as close as possible to the original.
  • All the submissions must be sent via e-mail, to the TBs mailbox setup for the purpose of this challenge, with indication of the applicant identification (full name and nickname if applicable), postal* and e-mail addresses.

    TBs TechREVERSE Challenge mailbox: challenge[at]technicbricks.com

Classification Criteria:
  • The winning participation will be the first submission sent, that exactly matches the LEGO official model subject of this challenge: model complete assembly, parts color, parts positioning and parts list.
  • If none of the submissions fill all the criteria above, it will be selected the first submitted one, that gets closer to the original, based the total mismatches counted.
  • There are different weights for each type of mismatch as a mean to differentiate the mismatches severity and increase the evaluation fairness.
    Each mismatch will sum a certain number of negative points (penalties) per occurrence, based on the respective mismatch type. The participation with less accounted penalties wins!

    Below the penalties per mismatch type:
    -5 points, Missing parts or subparts (so that you do not get tempted to avoid guessing on hidden parts just because it may lead to more mismatches than using wrong, extra or misplaced parts).
    -3 points, Wrong parts or subparts (includes friction/frictionless differences).
    -3 points, Extra parts or subparts.
    -3 points, Parts or subparts misplacement (deviation and/or orientation).
    -3 points, Wrong color used for a part or subpart (if element visible at some of the pictures available).
    -2 point, Wrong color used for a part or subpart (if not visible from any of the pictures available).
    -1 point, Every other eventual situation not covered above (e.g.: wrong spring strength, significant routing deviation from the original on flexible elements, etc.).
  • Classification (penalties sum) may not go through all the mismatches until the last one, once the amount gets too high and it turns clear the participation won't get among the ones granted with a final prize.

Schedules:
  • All the submissions must be sent to the mailbox above indicated, in the next two weeks. Thus before the 28th of November 2012, 16:00 CET**.
  • The organization reserves the right to extend or shorten the submission period, if there is a reasonable justification (e.g. too few participants, leak of the actual model or instructions).
  • Final results are expected to be published by mid of January 2013 (exact date may vary depending on the amount of submissions to the contest).

Prizes:

  • As usual the prizes will be some of the upcoming new LEGO Technic sets, signed by their respective designers. The details about these will be announced shortly.

Exceptions:
  • In the event of any eventual leak with further official details about this model, during the contest submission period, it may become a justification to close the submissions period anytime earlier.
  • Any eventual issues not foreseen in the contest rules, shall be evaluated and decided by the board of TBs editors.
  • The organization reserves the right to cancel the contest at anytime, if participation quality levels are not getting satisfactory.


Take part of the fun!

Edit:
Once the is now an evidence the additional details about this and other 2013 LEGO Technic models may arise at any moment, it turns that the Challenge may stop also at any moment, being considered only the submissions made until then.
Thus and because some are working hard on this, but afraid they won't be able to submit their work when it is 100% finished, it has been asked for the possibility to submit more that one entry, to allow the submission of preliminary work.


Considering the facts we have exceptionally changed the rules a bit in order to allow up to two submissions per participant, while the TechREVERSE Challenge lasts. Only the last participation will be considered.

Yay, LDD is still allowed! I'll definetely enter again, and I hope I win something this year. Third time lucky, I hope.

Philo said...

Ouch! this one is tough! Not only panels hide inside completely, but most parts are stickered, blurring lines...

Fernando Correia said...

I know!... hence I wrote we have a true Challenge this time. :) :/

Don't forget to look to the parts visible on the B-model. Usually they are all used in the main model too.
Although I don't have any insight whether it is the case here or not. Just speaking from what it is the usual.

Best!

Philo said...

Yes, it does help... a bit!

AVCampos said...

Also, this should go without saying, but I suppose it's not necessary to reproduce the stickers... ;)

Algirdas Lašas said...

Hm... and there won't be any more images... or at least better quality of box image... Because outside I almost have (except cockpit is not yet clear... But inside... It's little bit hard. I'm thinking - there is any connection between wheels and propeler?

Fernando Correia said...

@Algirdas

So far is the only image available and likely there won't be anymore till the end of the Challenge.
At least we hope there won't be something that reveals all the secrets.

You can look at the image from the B-model to get some hints.

crowkillers said...

Toys R Us had this set and the Race car Pullback set online a few days ago... My wife ordered a few of each...

Fernando Correia said...

Hopefully she won't get them that soon... :)
Some retailers like to advertise the news quite in advance, to gain some advantage.

crowkillers said...

They shipped out and are scheduled to be delivered today... I'll email you some pictures...

Algirdas Lašas said...

crowkillers: I'm not sure if publishing these pictures would be ok.. but if there was possible to order and people ordered this set already, and got it, it would be unfair to compete with them :)

Algirdas Lašas said...

Ok, I've checked - there was really possible to buy it through toyRus. And there were better quality box image and additional image in similar angle... I could send these images personally (if you need them). I don't know if it's good idea to explain how to get them until we decide, that that's these images are ok.

Fernando Correia said...

As soon as I get something more from Paul, probably the right thing to do, is to shut down the competition for this year...

Lesson learned! Next year this should start a few weeks earlier.
Something I need to clear with LEGO the next time, to assure it is done timely.

Shimon430 said...

After all the time I spent revealing pixels, got most of the b model... Really dissappointing to hear

Fernando Correia said...

If some entries are sent before we get evidence of the sets being out there, they might be considered.

JTZshokunin said...

Sad news...

Just out of curiosity though, did you know that the ribbed hose can't flex in LDD? Would you have overlooked that?

Luc2000 said...

Well, I found the "new" pictures from the Toys R Us website, but they are just better quality pics of the box/art and a picture without box, but in the same angle. I think you should post them here on the blog. If someone will post pictures of the one he bought, it´s probably better to end the contest.

Is it OK if I submit an early submission, just because it isn't clear when this contest ends?

Fernando Correia said...

@JTZshokunin

If the ribbed hose can't flex in LDD, you should leave it straight. It will be considered accordingly!

Fernando Correia said...

Though question Luc2000!... :)

We need to be flexible and adapt to the circumstances.

I'll make this an exception this time, and each participant could submit a maximum of two entries while the contest lasts. Only the latest one will be considered.

Will change the post accordingly.

Fernando Correia said...

And yes, usually when there are additional images, they're like you described and do not add much.
At least for the first one.

Can you provide a link to the new image?
I'm not getting it. :/

crowkillers said...

We got the sets today, well half of them.. They sent us the 5 Pullback racers, but not the Hovercrafts... Tring to find out what the story is with that...

Fernando Correia said...

Hmm...

Either they will arrive separately, or somehow they do not yet have them to send. :/
Both ways we will have some more time to keep the Challenge running. :P

Luc2000 said...

The correct hoses aren't available in LDD. I'll give a detailed description, just as I did last time with the parts that weren't available.

Not sure if this link works:
http://webcache.googleusercontent.com/search?q=cache:2c81xNiu6BAJ:www.toysrus.com/product/index.jsp%3FproductId%3D16803786+&cd=1&hl=nl&ct=clnk&gl=nl

And the link for the racecar. I expect some detailed pics of this one from you, crowkillers :)
http://webcache.googleusercontent.com/search?q=cache:ilVRmHmcUs8J:www.toysrus.com/product/index.jsp%3FproductId%3D16803836+&cd=2&hl=nl&ct=clnk&gl=nl

crowkillers said...

I started a thread over at eurobricks that we can update the new part numbers throughout the releases of the new sets...

I have the new Panels numbers listed along witha scan of the 42011 parts list...

Fernando Correia said...

And the first entries started to come in today! :D
